ICE-PICK.

Specication of Letters Patent.

Application led August 24, 1914. Serial No. 858,206. I

T0 all whom it may concern Be it known that I, ALEX MIKLos, a subject ofthe King of Hungary, residing at Columbus, in the county of Franklin andState of Ohio, have invented'certain new and useful Improvements inIce-Picks, of which the following is a specification.

This invention relates to certain new and useful improvements inice-picks.

The primary object of this invention is to provide a spring-mounted pickin which the pointed member is automatically restrained from revolvingbymeans of a spring element of the device.

A further object is to provide an ice-pick construction in which all ofthe elements may be readily disassembled including a compression springfor the pick and an automatic locking means therefor.

A still further object is to provide a pick adapted for breaking up ice,and that is cheap and easy to manufacture but which is so constructed asto cushion the hand of the operator when forcibly driving the pickagainst the-vice.

Vith these general objects in view and others that vvill appear as thenature of the invention is better understood, the same consists in thenovel combination, and arrangement of parts to be hereinafter more fullydescribed, illustrated in the accompanying drawings, and set forth inthe appended claims.

In the drawings forming a part of this application and in whichlike-designating characters refer t0 corresponding parts throughout theseveral views, Figure 1 is a longitudinal central sectional view of thedevice. Fig. 2 is a side elevation of the spring casing detached. Fig. 3is a side elevation of the casing mounting means detached. Fig. 4 is aperspective View of the engaging disk for the pick removed therefrom,and Fig. 5 is a perspective view of the end cap of the casing.

Referring more in detail to the drawings, the device broadly consists ofa handle 10. preferably formed of Wood, and having the pointed metallicpick 11 mounted therein. The handle 10 is provided with an enlarged bore12 extending axially thereof, and having removably fitting therein atubular casing 13, the closed top 14 of which forms the engaging end ofthe handle for grasping by the operator. i

A cap 15 is removably positioned in the open end of the casing 13, andis secured by means of opposite screws 16 projecting through openings17, positioned adjacent the'I casing end, and projecting into thescrew-threaded opening 18 in opposite sides of the said cap.

A helical spring 19 is positioned compressed within the casing 13 andbears upon the adjacent surface of a follower disk 29, 'which isslidably positioned within the said casing. The lower face of the disk20 is provided with a plurality of radial ribs 21, adapted to seat andl.engage in complementally formed radial grooves 22 in the adjacent faceof the casing cap l5.

The pointed pick 11 has a threaded blunt i end 23 adapted to bepositioned through the longitudinal bore 24 of reduced diameter.

and forming a continuation of the enlarged.

bore l2, the said pick end extending through a central perforation 25 ofthe casing cap, and attached by its screw-threaded connection to thesaid disk 20 Within the central screw-threaded perforation 26 thereof.

A bushing of the form illustrated in Fig. 3 is provided with the tubularportion 27 Patented Mar. 23, 1915.-

adapted to be inserted through the borev 24 and screw-threaded into theopening 25 of the casing cap,-Which opening is screwthreaded for thereception thereof. The ferrule 28 forms a part of the'bushing and isvadapted to protect the inner end of the handle 10, While the pick 11 isslidable Within the bushing.

The complete operation of the device will be apparent from the presentdetailed description in that the elements being assembled as bestillustrated in Fig. 1, the spring 19 normally holds the disk 20 and cap15in contact with each other and with the ribs 21 the cap when the saidribs and grooves arev brought in proper alinement with each other byimparting a partial revolution to the pick 11. By grasping the handle 10in the hand, the pick 11 may be violently contacted with the ice for thepurpose of separating and breaking the ice, and as will be apparent, thespring 19 pressing against the end disk of the pick, cushions the impactof the blow by imparting resilient inward relative movement to the pickslidably Within the handle.

It will thus be seen that an eflicient pick is provided, and While theforms of the inven tion herein shown and described are what are believedto be preferable embodiments thereof, it is to be understood thatchanges may be made therein without departing from the spirit and scopeof the invention as set forth in the claims.

What I claim is 1. An ice pick comprising a handle having a longitudinalcentral bore, a tubular :casing within a portion of said bore, andhaving an overlapping closed end at one end of the handle, a cap havinga screw threaded opening secured in the open end of said casing, abushing upon the opposite end of the handle, and having an inwardlyprojecting portion Within said bore, and screw-threaded into said cap, apick slidably mounted through said bushing and extending into saidcasing, and an expansion spring within said casing normally engaging theinner end of the pick.

2. An ice pick comprising a handle, a tubular casing carried b saidhandle, a closure cap at one end ofy the casing having a centralperforation therethrough and rovided with radial grooves on its innerace, a disk slidably mounted within said casing, depending ribs uponsaid disk adapted for engaging the adjacent side of said cap, and inseating engagement with said grooves, a pick extending through said capperforation, and attached to said disk, and an ex; pansion spring withinsaid casing engaging the said disk.

In testimony whereof I aliX my signature in presence of two witnesses.

ALEX MIKLOS.
